1.02 SUBMITTALS: Submit the following in accordance with

Section 01 30 00 “Submittals.”

A. Dredge Operations Plan: Submit a detailed dredge and disposal operations plan (DOP) of the entire dredging and dredge material disposal operation including a list of equipment, environmental controls, means of transport, and means and locations of intermediate storage or handling of dredge material. The DOP shall adhere to the permit requirements from the U.S. Army Corps of Engineers and shall include, at a minimum, the pre- dredge hydrographic survey, volume calculations, disposal locations, equipment types, a Notice to Mariners, and solid debris management plan.

Provide plans and procedures should gale force winds or higher be forecast. Precautions shall include, but not be limited to, closing all openings, removing all loose materials, tools and equipment from exposed locations, anchoring and tying down barge and pipeline.

This submittal is required 20 days prior to start of work and must be approved by the Corps prior to initiating the work.

B. Hydrographic Survey: Submit results of hydrographic surveys taken before and after dredging. The hydrographic surveys and related drawings must include the dredged prism and the Smuggler’s Cove disposal site. The pre-dredge survey submittal is required no later than 20 days prior to dredging operations and the post-survey submittal is required prior to final acceptance of the completed work or 5 days after dredging is completed.

Include areas to be dredged with over depth allowances;

existing depths; estimated quantities to be dredged for the project; and estimated quantities for over depth. A post-dredge hydrographic survey is required within 30 calendar days of the last disposal activity. Include the Corps permit number, dates of dredging commencement and completion, and actual quantities dredged (identify project depth and overdepth quantities).

Hydrographic survey procedures (positioning modes, EPS calibration, accuracy requirements, depth measurements calibration, and data reduction, adjustment, processing and plotting, etc.) shall conform to industry standards similar to, or more stringent than, those found in Army Corps of Engineers Manual EM 1110-2-1003 for Hydrographic Surveying and published November 30, 2013 (http://www.publications.usace.army.mil/USACEPublications/ EngineerManuals.aspx). The contractor is responsible for installing any survey points required and shall include that information on the drawings. If necessary, a tide board shall be installed and will remain at the facility.

Include a typical cross section(s) of the dredge footprint on the drawing. The survey shall locate the shoreline including mean higher high water (MHHW) and MLLW and show it on the cross section of the survey drawing. Locate all in-water structures outfalls, cable crossings or other man made features within or adjacent to the dredge footprint and include these structures within the hydrographic survey drawing. Drawings shall be provided in AutoCAD version 2017 file format (.dwg and .xyz) using the Civil Engineering Unit Oakland standard template (Figure 1), and in Adobe Pdf.

C. Dredge Volume Calculations: Submit results of actual gross and design volume of dredged material Cover sheet shall be signed, dated, and sealed by licensed surveyor.

D. Post-Dredge Report: Within 30 days after the completion of the project, the Contractor shall submit a post-dredge report to document the project’s execution. This report will be submitted to the regulatory agencies to satisfy permit requirements. At a minimum, the report will include calculated final dredging volume based on the pre and post dredge surveys, copies of the all hydrographic surveys, maps of the dredging footprint, dates of work, any noncompliance issues, required monitoring logs, environmental permitting compliance documentation, biological monitoring logs, and the disposal location of the dredged material..

1.03 ARTIFICIAL OBSTRUCTIONS: The USCG anticipates debris such as, but not limited to, metal bands, pallets, pieces of broken cable, rope, hose, and broken piles. The Government has no knowledge of existing wrecks or wreckages; however, there are remnants of a security barrier towards the outer edges of the dredge footprint. These have been identifies in the provided drawing. Furthermore, the U.S. Navy will clear the debris present at Smuggler’s Cove to remove existing fire pits and scattered rock. Prior to dredging, the Contractor shall survey and/or rake the dredge and disposal areas, and remove debris encountered. Debris removed from the dredge area shall be removed from the water. Explosives shall not be used under any circumstance. Disposal of debris shall be the responsibility of the Contractor and disposal shall be outside the limits of the USCG Mooring Ballast Point property.

1.04 QUANTITY OF MATERIAL:

A. Overdepth Dredging: To cover unavoidable inaccuracies of dredging processes, removal of material to a depth of two feet below the elevation -30.0 feet MLLW depth specified and within the dredging limits will be allowed.

B. Side Slopes: Side slopes at the side limits of the dredge area shall be 3:1 (horizontal: vertical) on the western half of the dredge footprint and 2.4:1 on the eastern side of the footprint, per Figure 1. Project the side slope from the dredged bottom elevation at the limits of the dredge area line outward until it intersects the existing bottom of the adjacent waterway. Dredging on side slopes shall follow, as closely as practicable, the lines indicated on the reference drawings.

C. Slides: In the event sliding occurs in any excavation after its completion but prior to its acceptance, the Contractor shall remove such portions of the slide at no additional cost to the Government. Particular attention shall be provided to the slope nearest to the eastern edge of the float dock.

1.05 OBSTRUCTION OF WORK AREA: The USCG Cutter Sea Otter is

homeported at the Mooring Ballast Point and may be present during dredging operations. For this reason, the Contractor is to keep close communication with the Captain of the USCG Cutter Sea Otter to ensure appropriate safety zones are observed. The USCG will coordinate with the Contractor to ensure dredging under the western half of the floating dock is conducted while the vessel is underway.

The Contractor will be required to conduct the work in such manner as to avoid obstruction to USCG operations and navigation. In case the Contractor’s plan so obstructs the navigable water as to make difficult, or endanger the passage of vessels, said plant shall be promptly moved on the approach of any vessel to such an extent as may be necessary to afford a practicable passage. Upon completion of the work, the Contractor shall promptly remove his plant, including pipeline, ranges, buoys, piles, pipeline, and other marks placed by him under the contract in navigable waters or onshore. The USCG will need access to the facilities during the work period and in some instances it may be an emergency. If required, the Contractor’s plant must have the ability to be maneuvered from the boat basin immediately following direction from the USCG.

PART 2 PRODUCTS

2.01 Not used.

PART 3 EXECUTION

3.01 INSPECTION: Inspect the work, keep records of work

performed, and ensure that gages, targets, ranges, and other markers are in place and usable for the intended purpose. Furnish, at the request of the Contracting Officer, boats boatmen, laborer, and materials necessary for inspecting, supervising, and surveying the work.

3.02 CONDUCT OF DREDGING WORK

A. Interference with Navigation: Minimize interference with the use of channels and passages. The Contracting Officer will direct the shifting or moving of dredger or the interruption of dredging operations to accommodate the movement of vessels and floating equipment, if necessary.

B. Lights: Each night, between sunset and sunrise and during periods of restricted visibility, provide lights for floating plants, pipelines, ranges, and markers. Also, provide lights for buoys that could endanger or obstruct navigation. If night work proposed, lights must be made available from sunset to sunrise for the observation of dredging operations. Lighting shall conform to the USCG requirements for visibility and color, and ensure lights point downward as not interfere with transient birds.

C. Ranges, Gages, and Lines: Furnish, set, and maintain ranges, buoys, and markers needed to design the work and to facilitate inspection. Establish and maintain gates in locations observable from each part of the work so that the depth may be determined. Suspend dredging when the gates or ranges cannot be seen or followed.

D. Plant: Maintain plant, scows, coamings, barges, pipelines, and associated equipment to meet the requirements of the work. Monitor and promptly repair leaks or breaks along the pipeline.

E. Dispose of Excavated Material: Provide for safe transportation and disposal of dredged materials.

Transport and dispose of dredge material in the area designated for disposal of dredged material. The deposit of dredged materials in unauthorized places is forbidden.

F. Method of Disposal: The material excavated from the boat basin shall be transported by hydraulic pipeline to the disposal location indicated. The use of floating and submerged discharge lines is authorized. The Contractor shall ensure compliance with the provision of this Specification Section and the regulatory permits. The Contractor must also ensure minimal disturbance of the shoreline areas.

G. Disposal in the Indicated Fill Area: Discharge into the disposal area shall be at the center of the disposal area.

No alternate disposal will be allowed. The Contractor will pump the material via pipeline to the indicated disposal site. Provide and maintain necessary bulkheads, dikes, ditches, spillways, and other construction necessary to confined and retain the fill in the dredge fill area.

H. Salvaged Material: Anchors, chains, firearms, and other articles of value, which are brought to the surface during dredging operations, shall remain or become the property of the Government and shall be deposited on shore at a convenient location near the site of the work.

I. Working in the Vicinity of Structures: The Contractor shall exercise caution when working in the vicinity of structures adjacent to and within the piers and bulkheads.

Repair of any damage resulting from excessive or improper excavation of the basin shall be the responsibility of the Contractor. When dredging to obtain the required dimensions might endanger any structure, the Contracting Officer, upon request, may reduce the required excavation in the vicinity of such structure.

J. Plant Removal: Upon completion of the work, promptly remove plant, including ranges, buoys, piles, and other markers or obstructions.

3.03 DISPOSAL SITE: Dredged sediment would be transported via a discharge pipeline to the U.S. Navy Smuggler’s Cove restoration site for both nearshore replenishment and beach nourishment. Smugglers Cove is located approximately 350 feet from the USCG pier at Ballast Point within the Naval Base Point Loma. The U.S. Navy proposes to create an artificial reef at this location in two Phases. Phase I- Interim Beach Restoration includes receiving the sediment from the USCG dredging project and storing it above -5.0 feet MLLW until they receive permits to implement Phase II. Phase II will be a separate action to this project and includes distribution of sediments below -5.0 feet MLLW, installation of the rock reef, and enhancement of eelgrass habitat.

A. Disposal: Transport the dredge sediment by hydraulic pipeline to the Smuggler’s Cove. Comply with all the requirements of the U.S. Navy for use of the facility. The U.S. Navy will clear the site of debris (existing fire pits and scattered rocks) prior to dredging.

Per engineering drawings provided by the U.S. Navy (Drawings CN101 through CN103), the Contractor is to deliver the sand to the beach and push it out using equipment, such as a bulldozer, to create a basin between the existing seawall and sand berm. The sand shall be laid out from +13.0 feet MLLW to -5 feet MLLW with the slopes shown in the drawing (12:1 between +13.0 feet and 0.0 feet, and 8:1 between 0.0 feet and -5.0 feet). The Contractor shall provide surveyors to ensure the sand is laid out in within the correct depths and slopes and shall include the survey of the layout areas pre-and post disposal. The final design must be included in the post-hydrographic survey drawing.

A standpipe weir that is sized to carry the return water from the slurry line will be placed and water will be decanted using this system to allow sediments to filter out of the water before entering the bay. As the sand trapped in the basin is pushed up to stockpiles to maintain the capacity of the basin, sand piles continue to drain and are then pushed forward to enlarge the basin and begin filling the beach. The final stage will be to groom the accumulated sand to the interim beach contours as shows on Sheet 2 of the Phase 1 Interim Beach Restoration plan set. The use of heavy equipment will likely require tidally timed work.

B. Turbidity: The pooled water decanted from the standpipe is anticipated to be clear and dredging in this manner with sand shoals may not require additional best management practices to pass turbidity standards. However, if necessary, a small turbidity curtain shall be made available to be placed outboard of the return water weir to force turbid water down a manner that would further improve water clarity.
